我正在尝试安装 rails 3.0.0.beta 并且遇到了这个问题:
justins-mac-: justinz$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
justins-mac-justinz$ rails -help
/Library/Ruby/Site/1.8/rubygems.rb:384:in `bin_path': can't find executable rails for rails-3.0.0.beta (Gem::Exception)
from /usr/bin/rails:19
justins-mac-justinz$ rails -v
/Library/Ruby/Site/1.8/rubygems.rb:384:in `bin_path': can't find executable rails for rails-3.0.0.beta (Gem::Exception)
from /usr/bin/rails:19
justins-mac-justinz$
关于这里发生了什么的任何线索？
最佳答案
sudo gem install railties --pre
关于ruby-on-rails - Rails 3.0.0.beta 安装问题 : can't find executable rails，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/2212259/
